REACH work in South Sudan in Constraints and Complexities of Information and Analysis in Humanitarian Emergencies Evidence from South Sudan report by Feinstein International Center, September 2018

Several organizations track displacement, and this information is useful, but the nature of the conflict means that populations in given locations
can change very rapidly and population movements often involve large numbers of people. Unfortunately large numbers of people moving in a short timeframe
are also likely to be indicators of extreme food insecurity. In many cases, information from the REACH project is the best information there is on the conditions of populations on the move, but this is qualitative information that is difficult to turn into numeric estimates. Conflict and the associated population movements often happen between the seasonal assessments so IPC projections are very time-delimited in the areas of South Sudan most at risk for famine.
